As long as you popped it in the freezer as fast as possible after cumming, when you thaw it using the method above, you have a few minutes of time after it's thawed in which the texture and color is as close as possible to fresh cum. The main point is, even fresh cum that's never been frozen, if left sitting for more than 15 minutes, loses its thick sticky texture and bright white color. The problem with thawing a huge chunk of cum is, while you're waiting all that time for the huge ice cube to melt, the cum that melts off first spends longer sitting, losing its fresh properties. When you thaw a thin chunk of cum like what I showed above, by submerging the baggie in warm water, it should take no longer than 5 minutes to completely thaw. This means, as long as you froze it quickly, the total amount of time the cum has spent in liquid state is relatively short. It doesn't give you a lot of time, but after 4 or 5 minutes in warm water, cut the corner off the baggie and pour the cum out, and you should see that it is slightly thick and sticky.

Also, the warmer the water, the faster the cum melts. But don't use water that's too hot, or the heat will destroy the texture and flavor even more. Experiment to see which temperature gives you the best results. You're going for the shortest thawing time possible. If it's totally liquid, and the full 5 minutes hasn't gone by yet, don't leave your cum in the water. Pull it out quickly and use it.

Just remember, freeze quickly, thaw quickly. That's the key. Hope that helps!
